Nimzovich changed the ideas of chess forever with his principles of hypermodern play in his book My System. This series teaches those principles that top player have been using ever since.
Also, the thing I hate THE MOST in chess games is losing a game in the ending that I should win. Advanced FBCC classes include endgame studies so that its members excel at winning endgames. Our players are better prepared for endgames than just about anyone else and often win games in the ending that they would otherwise lose.
Hypermodern Play 2 (out of 6) No prerequisite needed.
